Abstract (en)
A polymer composition contains:(A) a conjugated diene-based polymer having a carbon-carbon unsaturated bond and exhibiting a value θ of 0.75 or more as determined by formula (i): θ=p+0.5×r/p+q+0.5×r+s wherein p, q, r, and s are respectively the proportions by mole of structural units represented by formulae (1), (2), (3), and (4) in the polymer:and(B) at least one component selected from the group consisting of water-soluble particles and water-soluble fiber.
